In the case of the missing dollar paradox there is actually no missing dollar. The prompt starts off with stating that the bill for the meal is $30, which is then evenly split between the three women. The reader then finds out that the actual price of the bill is $25. So the cashier gives the waiter $5 to give back to the three women. The waiter ends up keeping 2 out of the 5 dollars, essentially acting as a tip and then gives each women $1 back. But what is missed is the $25 bill that has technically already been paid. The cashier still has the $30 that the women paid and the cashier only had to give back the $5 that needed to be returned. The prompt then goes on to say that the three women try to split it evenly by all paying $9 which doesn’t make sense since the cashier never gave them their $30 back, only the $5 that needed to be returned. So each woman got $1 back and the waiter received $2 as a tip. There is no missing dollar here.
